A Brooklyn man who used a JetBlue flight attendant as a punching bag in a drunken assault says he is a victim — of cyberbullying.

Antonio Ynoa, 24, claims Google, YouTube and an online video company called Daily­motion violated his privacy by posting a video of the attack online, according to a lawsuit.

Ynoa was arrested and sentenced to three months in jail for the 2011 attack on flight attendant Elio Cabral, in which he started poking at the JetBlue attendant and then slugged him three times in the face.

The assault began because Cabral had asked Ynoa to stop drinking on the JFK-bound flight out of the Dominican Republic.

Released from jail in January, Ynoa says the big tech companies were taking advantage of him, according to a Brooklyn federal lawsuit.

Ynoa, who is acting as his own lawyer, is seeking $200.5 million in damages.
